在Qt中显示窗口,而不窃取焦点 [英] Show window in Qt without stealing focus
问题描述
当用户没有使用第二个显示器时,我使用Qt库在第二个显示器上显示幻灯片。一个例子是用户在第一个监视器中玩游戏,并在第二个监视器中显示幻灯片。
I'm using the Qt library to show a slideshow on the second monitor when the user isn't using the second monitor. An example is the user playing a game in the first monitor and showing the slideshow in the second monitor.
问题是当我在Qt中打开一个新窗口时自动从之前的应用程序窃取焦点。有没有办法防止这种情况发生?
The problem is that when I open a new window in Qt, it automatically steals the focus from the previous application. Is there any way to prevent this from happening?
推荐答案
我花了一段时间才发现它, c $ c> setAttribute(Qt :: WA_ShowWithoutActivating);
It took me a while to find it but I found it: setAttribute(Qt::WA_ShowWithoutActivating);
这会强制窗口不激活。即使使用 Qt :: WindowStaysOnTopHint
标志
This forces the window not to activate. Even with the Qt::WindowStaysOnTopHint
flag
